Abstract
1354038 Dichlorobutenes E I DU PONT DE NEMOURS & CO 17 May 1972 [27 July 1971] 23256/72 Heading C2C Dichlorobutenes are obtained by reacting butadiene with chlorine in the vapour phase at 80‹ C. to 350‹ C. (e.g. at 0-50 p.s.i.g.) in the presence of at least one fluorocarbon having a boiling point at atmospheric pressure in the range - 50‹ C. to 50‹ C., the mole ratio of fluorocarbon to chlorine being in the range 1/1 to 500/1. The mole ratio of butadiene to chlorine is preferably in the range 1/1 to 50/1. Preferred fluorocarbons are CFCl 3 , CF 2 Cl 2 , CF 2 Cl, C 2 F 4 Cl 2 , C 2 F 4 Br 2 , C 2 F 5 Cl, C 3 F 3 Cl 3 , octafluorocyclobutane and mixtures thereof.
